Hi again.
I just tryed to hook up a DIY CO2 reactor? up
Using a 1 litre bottel and sugar yeast mix.
I cut the top of a plastic bottel and layed it on it's side with some gravel in it so it won't float away when it gets some air in it.
I want to get a powerhead and run the CO2 through that eventually.
I will see how this works.
Also I just have two standard Fluros lighting the tank.
as you see in the pic.
Is that enough?
As I can not afford better lights.

you will need a whole lot more bottles for a 6ft tank. i have a 4ft, 50gal tank and have 4 2l bottles hooked up, 2 on each end.

"enough lights" depends entirely on what sort of plants you want to grow. how many watts are your lights, and how many gallons is your tank? if it is about 1 watt : 1 gallon, then you are good to go for low light plants.
